Spacecraft data:

Description:

• SpireGlobal Lemur-2 satellites with ship tracking and GNSS-RO meteorology payloads.

Mission details:

• Lemur-2 is the initial constellation of low-Earth orbiting satellites built by Spire.
• The Lemur-2 satellites carry two payloads: STRATOS GPS radio occultation payload and the SENSE AIS payload.
• The SENSE payload enables tracking ships worldwide by receiving their AIS signals. Spire satellites, which orbit close to Earth's atmosphere, listen for GPS satellite signals - which are impacted as they pass through Earth′s atmosphere. Using a process called GPS radio occultation, Spire measures the change in GPS signal readings to calculate very precise profiles for temperature, pressure, and humidity here on Earth.
